Why is "stm32f4xx.h" missing when I try to build my model for the STM32F4 Discovery Board?

Here is the associated message from the diagnostic viewer.

In file included from <command-line>:0:0: C:/ProgramData/MATLAB/SupportPackages/R2019a/toolbox/target/supportpackages/stm32f4discovery/include/stm32f4discovery_wrapper.h:18:10:
fatal error: stm32f4xx.h: No such file or directory #include "stm32f4xx.h" ^~~~~~~~~~~~~ compilation terminated.

This message causes the build process to terminate with the following error:

Error(s) encountered while building "DiagLedLogic_mil": ### Failed to generate all binary outputs.

This issue could be resolved by installing the STM32F4DISCOVERY Board firmware package following the steps in the "Hardware Setup" pane of the "Embedded Coder Support Package for STMicroelectronics Discovery Boards".

You can open the "Hardware Setup" dialog using the steps found here:
